Carry On humour: just what the doctor ordered for the BBC Trust? Photograph: ITV/Rex Features

It seems like the BBC Trust doesn't just have a problem with the corporation's management on its hands – it also seems to be stuck in some sort of time warp. Take this ruling: double entendres such as "jugs" and "melons" are acceptable before the watershed, the Daily Telegraph reports that the trust has ruled, but references to threesomes, tantric sex and "slutty Sundays" are more "questionable". The reasoning? "Seaside postcard" humour is OK. Clearly the BBC didn't ask women. It seems that the Liberal Democrats aren't the only ones with alleged sexism on their hands.
